Help. CUT on Tyre tread. Repair or replace?

I was inspecting the bike this morning and I found this cut on the rear Tyre. It doesn’t seem to be very deep. Can I repair it or should I replace it? Tyre is new has 500 miles and 1 track day. Thanks

 

I'd view it as insignificant because it doesn't seem to even reach the depth of the tread. I'd have no reservation about track or road. (Just opinion though)

 

I wouldn't be too worried about that, just keep an eye on it. Chances are it'll be worn away in the next 500 miles.

 

Agree with previous comments, looks like normal wear and tear, nothing too serious.

 

If your as tight as me you'll run it

 

Looks like it's just clipped a small stone or something on the edge of the tread. Nothing worry about as said no where near the depth of the tread

 

Thanks for the advise guys. I will just keep an eye on it.
